The ASTM A194 Grade 6 Washer is one of the fasteners in this specification. This specification covers fasteners of 3mm to 200mm length with sizes ranging from M02 to M160 according to different standards such as DIN, ISO, JIS and others. The ASTM A194 Gr. 6 Nut comes with unified threads and metric coarse thread types. The thread type, material, dimensions and mechanical properties of the ASTM A194 Grade 6 Fasteners vary with the application requirements. The material can be quenched and tempered for high hardness. The applications include high wear and tear applications such as transportation, concrete work, construction, engineering, engine parts and others. The ASTM A194 Grade 6 properties make these fasteners available for a wide range of application types.

ASTM A194 Gr 6 Hex Nuts are made up of austenitic grades and martensitic grades of stainless steels. The material of this grade of nuts has carbon, manganese, phosphorus, sulfur, silicon and 11.5% chromium minimum in the composition. The SA 194 Gr 6 Nuts have minimum tensile strength of 550MPa and minimum yield strength of 240MPa. The hardness of the nuts is 223BHN.
